Vector Information

Multiple species of fleas may feed on humans including the human flea Pulex irritants, the dog and cat fleas Ctenocephalides canis and C. felis respectively, the oriental rat flea Xenopsylla cheopis, and the sticktight flea Echidnophaga gallinacea. In the US, the flea of most concern is the Oriental rat flea as these fleas are able to transmit plague to humans. Fleas eat the blood of mammals and birds. The primary host is dependent upon the flea species, but in the absence of the primary host, fleas will bite other hosts. Fleas moving to new hosts is the most common way for outbreaks of disease in humans to occur. A primary host may have low levels of disease circulating within it, but the disease does not cause an excessive host die-off until it enters a new species. Flea infestations are preventable.

*Disease transmission varies locally. This map depicts where vectors can be found geographically and provides information about diseases these vectors might carry. Vectors might be present in a state or locality, however, and not be carriers of any particular disease. In addition, identified vectors may have a presence in a state, but may not be found throughout that state.
